CUIUTAINER, ESPECIALLY CANISTER, FOR AUTOMOBILE DRIVING LIQUIDS.

application filed. September 24, 1925, Serial No. 58,389, and in Germany April 4, 1925.

The present invention has for its object to provide an improved form of container, more particularly a canister for automobile driving liquids, as gasolene, oil or the 111cc. A novel. feature of said container or canister isits unsymmetrical comically rounded cover. An aperture tor filling and discharging the liquid is provided on the steeply sloping part of this cover. A vent tube adapted to permit air to pass in or out of the container or canister has one of its extremities connected to the upper part of the aperture for filling and discharging the liquid, said tube extending in a anting direction to the opposite part of the canister cover. Adjacent the other end of said tube is provided an opening for the passage of air, said opening being at a point higher than the lower edge of the filling and discharge aperture. Thus, since the container or canister can not be filled higher than the lower edge of its filling aperture, it is evident that the inner opening of the venttube Will always be above the level of the liquid, that is, in the air space which will always normally exist within the top of the canister.

When the canister is used for the dis charge of oil, air is continuously admitted into the interior oi? the container through the vent tube connected near the upper part of the discharge aperture, so thata gurgling and bubbling of the oil during its discharge.

is prevented.

in case the oil. has entered the vent tube during the conveyance of the canister, the oil would, at the beginning of its discharge, he drawn oil from the vent tube into the interior ot the canister by the vacuum created or produced in the interior of the canister, and in consequence said vent tube would constantly be open so that the air could always enter into the canister.

Experiments have proved that even the heaviest oil can be discharged fromv the canister 'lf'orming the object of the present invention within the shortest time, so, for instance, lbs. (equal to kilograms) of heaviest oil were discharged within seconds. l l ith the use of the canisters lmown up to the present, l minutes at least were itiecessary for said discharge.

The object of the present invention is represented in one example of construction in the drawing annexed to the description.

Fig. 1. is a longitudinal elevation, partly in section, and Fig. 2 a front elevation of the container or canister. Fig. 3 represents in longitudinal section the upper part of a modification of the container and Fig. i a section taken through the line i l--13 of Fig. 3. Fl 's 5 and 6 represent similarly details 01 a ther modification. of the container shown in Figs. 3 and a. i

As seen from the drawing, 6 is the con tainer or canister, at its cover oi an unsy1nmetrical and conically rounded shape and e the filling and discharging aperture ar-- ranged in the steeply sloping part of the cover mentioned. 0 is a head surrounding the aperture 0 and arranged tor the dis charge of the. liquid. .(Z. is a hollow or solid stopper provided onits outer surface with a thread to be screwed into the head 0. f is an opening arranged in the upper edge of the aperture 6 provided in the rounded cover a, said opening being in connexion with one end of the interior vent tube 9. Said tube extends in a slanting direction towards the opposite part of the cover a and is provided near its other extremity with an ragening it tor the admission and issue of air in such a manner that said opening is situated within the air-chamber below the cover and at a higher level than the loweredge of the admission and discharge-open 111g 6.

In the modification of the container or canister shown in Figs. 3 and 4, the stopper d screwed into the head 0 is formed as a carrier for the discharge-spout 7c and a pas sage 2' is arranged in its bottom.

The small opening 7 arranged within the unsynnnetrical conical part oi the cover a is, for the purpose of discharging or empty log and filling the container or canister, brought in free connection with the opening 2' of the stopper 01 when screwed into the head 0. When the canister is not in dispenslug use the stopper (2 is turned so as to bring the opening 71 out oi register with the opening f, as illustrated in Fig. l.

Fig. 5 represents in longitudinal section and llig. (l in transverse section to line C-D another modification oi the stopper iarrying the spout it. lllccording to this n'iodification the opening 7" in the bottom of the head 0 and the opening 2' in the bottom of the stopper (Z are maintained, but a second. opening 15 is provided, diametrically opposite the said opening 2'. within the stopper-bottom. When the spout L is in position suitable to discharge the canister the opening 2' is situated in front of the opening f and air can enter through both openings and through the vent tube 9 into the air-chamber within the cover a.

If however the sto per d together with the spout k is turned into a position suitable for filling the canister (Fig. 5) the opening z" is adjusted in front of the opening f, so that during the filling of the canister the air canissue outwardly by the tube g.

' In case the canister is not in use, the stopper d with the spout 70 may be removed by unscrewing it from the head 0 and the apertures e and f in the wall of the cover a may then be closed by a stopper d, as shown in Fig. l. i V

sWhat I claim is:v

1. A container otthe character described comprising, an unsymmetrical iconically rounded cover, a filling and discharge aperture in the more steeply sloping side thereof'and a vent tube within said cover, said tube having an open end adjacent the upper edge of the filling and discharge aperture,

extending in a downwardly slanting direction toward the opposite side of the cover and being provided near its other end with an air inlet and outlet opening, said opening being at a level higher than the lower edge of the filling and discharge aperture.

2. A container of the character described comprising, an unsymn'letrical eonically rounded cover, a filling and discharge aperture in the more steeply sloping side there of, a vent tube within said cover and connected with an opening adjacent said filling and discharge aperture, and a. stopper adapted to be applied to the aperture, said stopper being traversed by a discharge spout and provided with a pair of oppositely disposed openings arranged to coincide alternately with the opening at the end of the vent tube, the one during the lil ing of the container and the other during the discharge thereot. In testimony that I claim the foregoing as my invention, I have signed my name this 10th day of September, 1925.
